Answer for The Sum() function in Tableau

https://365datascience.com/dwqa-answer/answer-for-the-sum-function-in-tableau-2/ -

Hi Nithin, 

thanks for reaching out! 

We need the SUM to calculate the entire Revenue and Gross profit for each month. 

Although the values in the table we’re displaying are an aggregate for each month for each of the years 2016 and 2017, the actual Revenue and Gross profit variables are not. That’s why we need the extra step and use SUM.

If you need a refresher you can check out the Creating a Table video https://365datascience.teachable.com/courses/360090/lectures/5519613

or examine the Tesla-sales-data excel file, if that’s easier.

 

Best, 

Eli
